- CARPET-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 273,130, dated February27, 1883.

Application filed January 2, 1883.

To all whom it may concern:

Be it known that I, GEORGE ll/IULLIGAN, of Taunton, in the county ofBristol and State of Massachusetts, have invented certain new and usefulImprovements in Carpet Stretchers; and I do hereby declare the followingto be a full, clear, and exact description of the same, reference beingbad to the accompan yin gdrawings, forming part of this specification,in which- Figure 1 is a side elevation of my invention, showing themanner of using it; Fig. 2, a top plan view of the same. Fig. 3 isabottom plan view of the toothed head; Fig. 4, a sectional view taken onthe line 00 m of Fig. 3.

Similar letters of reference in' the several figures denote the sameparts.

My invention consists of an improved carpet-stretcher constructed andadapted for operation substantially as I will now proceed to describe.

Referring to the accompanying drawings, A B represent two arms, jointedtogether by a cross-bolt, a, upon which works a set-nut, b. To the arm Ais connected a cross piece or head, (3, suitable brace-rods, c,extendingfrom the arm to the head near its ends, as shown,forstrengthenin g the connection between the parts. Upon the under faceof the head 0 is secured a plate, D, preferably 'of metal, having two ormore openings, d, through which project groups of sharpforwardly-inclined prongs or teeth 0, connected preferably to a flexiblebacking, E, interposed between the head and the plate 1), as clearlyshown in Fig. 4. The outer end of the arm B is perforated for thepassage of a bolt,f, and from this bolt depend links F, which areperforated at their lower ends for the passage of a bolt, G.

H represents a bar having a series of holes, h, extending laterallythrough it at intervals throughout its entire length, and carrying atone end an end piece, I. The cross-bolt G is adapted to pass through thelinks F and through one of the several holes h, and to form, inconnection with the links, an adjustable pivotal connection between thearm B and the bar H.

In putting down a carpet one edge of the carpet is tacked near thebase-board at one side of the room, and the carpet is spread out (Nomodel.)

and drawn with the hand, as near as may be, to the opposite side of theroom. The end piece, I, of the bar H of the stretcher is then placedagainst the base-board at the tacked edge of the carpet, and thecross-bolt G is adjusted through the links and through one of the holesh of the bar H, with the head 0 bearing the prongs or teeth engaged withthe carpet near its edge at the opposite side of the room. The operatorthen be'ars down upon the joint of the arms A B until the arms aresufficiently depressed and extended to cause the toothed head to stretchthe carpet and bring its edge to the opposite base-board, and when thisis accomplished he tightens up the nut I), thus clamping the arms ABsecurely in their adjusted position, and enabling him, with hammer andtacks, to secure the edge of the can pet. This operation is repeateduntil the carpet is secured all around.

The adjust-ability of the cross-bolt G in the various holes of the bar Hgives the stretcher a wide range of action and enables it to be employedeffectively in rooms of'varyin'g lengths, while the connection of thearms A B with each other and with the bar H through the adjustablepivoted link F renders thewhole stantially as described.

2. The combination, with the head, of the plate secured to its underside, and having the opening and theforwardly-inclined prongs or teeth,and its flexible backing between the plate and the head. substantiallyas described.
